Putting a generator away for the season the right way — stabilize the fuel and run it through, or run the carburetor dry, plus where to store the machine, in plain English. Rather have a hand? My number is (330) 200-8042.
Long-Term Fuel Storage and Draining, at a Glance
Most fuel advice focuses on the cans in the shed, but the fuel already inside the generator needs its own plan before a long rest. This guide covers stabilizing and running it through, running the carburetor dry, and choosing a safe storage spot in plain English. There's a printable 29-page version up top.
Common Questions
1 Do I need to do anything with the fuel already in my generator?
Yes — it ages the same way fuel in a can does, and it's the fuel most often forgotten. Stabilizing and running it through, or running the carburetor dry, are the two honest options.
2 Should I stabilize the fuel or run the carburetor dry?
Check your owner's manual — manufacturers differ on which they recommend for a given engine. Both work well when you follow the method your model prefers.
3 Where should I store my generator for the off-season?
Somewhere cool, dry, ventilated, and covered, away from living space and any flame or ignition source, and off bare damp concrete if you can.
4 What about the battery on an electric-start generator?
A battery left fully discharged for months can be damaged. Check your manual for how the manufacturer recommends maintaining it during storage.
5 Is this the same as rotating my stored fuel cans?
No. Rotating cans is about your ongoing fuel supply; this guide is about the fuel already inside the machine when you put it away. Both matter, on different schedules.
6 What do I do with a propane generator for storage?
Simply disconnect the cylinder and store it outdoors, upright, the same as any propane cylinder not in use. There's no stabilize-or-dry decision with propane.

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
